the end part corrupted sound if due to a bad dump (tested on real A500), but also if no clean start and cycle exact enabled with a good dump.
This demo has buggy trackloader. If it finds sector header at the end of track buffer (sector contents ends early), it detects checksum error correctly but then it sets disk side selection to zero and retries.. So if this error happens on side 1, it retries from wrong disk side..

This can happen on real hardware too, depending on rotation speed of drive that was used for writing and reading because trackread buffer is too small.
